SPECIFIOATIONforming part o f Letters Patent N0.N702,`180, dated .Tune 10, 1902. t Application lred February, 1902. Serial No. 93,209. (No model.) l

To all whoml it may concern.-

Beit known that I, RUDOLF A. BooKHoor,

a citizen of the United States of America, re

siding at Lexington, in the county of Fayette and State of Kentucky, have invented cer-A tain new and useful Improvements in Checks, of which the following is a specification.`

This invention relates to chocks for use on track-rails to prevent movement of car should the brakes be inadvertently released.

The object of the invention is to produce a chock which is readily attached in place on the rail and which may be speedily removed.

Furthermore, the object of the invention is to produce a chock which will have a gripping action on the rail, caused by the contact of the car-wheel With the nose of the chock.

Furthermore, the object of the invention is to produce a chock which willpossess advantages in points of simplicity, efficiency', and durability, proving at the Sametime comparatively inexpensive to produce and sustain.

With the foregoing andother objects in view the invention consists in details'of construction and in the arrangement and combination of parts to beherein'after more fully set forth and claimed.

In describing the invention in detail refer-` ence will be had tto the accompanying drawings, forming part of this specication,where in like characters denote corresponding parts in the several views, and in which- Figure l is a view in perspective of a chock embodying the invention applied'to va rail.'

Fig. 2 is a plan View thereof. Fig. 3 is airinside face view of one section of the chock.A

In the drawings, l denotesthe sections of the chock which are attached to the rail. Each section has a recess 2 to receive the rail-head, and shoulder 3, which fits under the head.

The heel end of the section is designed to clutch the under surface of the rail-head.

The nose 4. of each section of the chock has a tapered under surface from the point 5, and when the wheel of a locomotive or' car contacts with the nose the clutch will be depressed and cause the edge 6 of the heel and the edge 7, formed at the junction of the straight portion'of the chock-section, and its tapered nose to grip the rail in a manner to prevent movement of the chock.

the rail and permit their ready removal.

From the foregoing it will be observed that -when a wheel contacts with the nose of the chock said nose willv be depressed and cause the body of the chock to more rmly grip the rail, this being a great advantage when the rails are worn small or are smooth.

The construction, operation, and advantages will, it is thought, Vbe understood from the foregoing description, it being noted that various changes may be made in the proportionsand details of construction for successfully carrying the invention into practice.

. Having fullydescribed the invention, Awhat I claim as new, and'desire to secure by Letters Patent, is

. l. In a chock, a body havinga recess to receive the head of the rail, a nose carried 4by the body, said nose being tapered upwardly to its end, and a rail-engaging edge forming `a fulcrum at the junction of the body and nose.

2. In a chock, a body having a recess forming a shoulder, said recess being flared `toward the rear, a nose carried by the body and tapering upwardly toits end, a fulcrum at the `intersection of the body and nose, and means forsecuring the body to the rail.

`In a chock, two sections clamped to a rail,`noses carried by the sections, and edges forming fulcrums, at the junction of the noses and bodies.

In-` testimony `whereof I `affix` my signature, in the presence of two witnesses, this 30th`day of January, 1902.
